WINDOW.

'SPECIFICATION forming part of Letters Patent No. 689,802, dated December 24, 1901.

Application filed July 20, 1901. Serial No. 693101. (No model-l Tad/ZZ whom it may concer-71,:

Be it known that I, ALBERT S. J HAYG'ooD, a citizen of the United States, residing at Las Cruces, in the county of Donna Ana and Territory of New Mexico, have invented a new and useful Window, of which the following is a specication. y

The present invention relates to windows,

and more particularly to the balancing and locking means therefor.

One of the principal features of the invention resides in means for vconnecting the sashes of the window so that each will form a balance for the other, said means being so constructed that the independent adjustment of eachsash is permitted, in which latter relation the connecting means serves as a lock for one of the sashes.

A further feature relates to means for automatically disengaging one sash from the other upon their movement to a predetermined position, so as to permit of theirindependent adjustment.

In order that the invention may be readily understood, the preferred form thereof is shown inthe accompanying drawings, and its construction and operation are fully described in the following specication. The invention is, however, not to be limited tothe eX- act construction shown and described, but is open to such changes and modifications as are allowed by the scope of the appended claims.

In the drawings, Figure 1 is a perspective view of a window having the improvements applied thereto. Fig. 2 is a horizontal sectional view throughv the same. vertical sectional view showing the windowsashes when closed. Fig. 4 is a similar view illustrating the upper sash when lowered whilethe lower sash is closed. Fig. 5is a vertical sectional view showing the lower sash raised and the upper sash lowered, with the` connecting means disengaged from said lower Sash. Figs. 3, 4, and 5 are all taken on the line X X of Fig. 2 looking in the direction of the arrow. Fig. 6 is a vertical sectional yview taken on the line YYof Fig. 2, but showing both sashes removed in order to more clearly illustrate the construction and arrangement of the several elements of the invention. Fig. 7 is a detail vertical sectional Fig. 3 isa view more clearly illustrating the construe;

ltion of the locking-bolt for the lower sash.

said sash being shown partlyin section. Fig.

10 is a perspective view'of the fastening device for the connecting-cord.

Similar numerals of reference designate Fig. 9 is a detail view of vone of the lower corners of the lower sash,

similar parts throughout Ithe several figures f of the drawings.

In order that the invention may be readily understood, a window-frame 10 is shown in which are slidably mounted the usual lower and upper sashes 11 and 12, separated from each other by parting-beads 13. Mounted in these partingLbeads, intermediate their ends and preferably, though not necessarily, at the point where the meeting-rails of the sashes coact when said sashes are in closed position, aregrooved pulleys 14,1ocated` in suitable casings 15. Connecting the sashes are cords 16 or other suitable flexible devices, said cords passing over the pulleys 14 and operating in longitudinal grooves 17, made for that purpose in the opposite side edges of the sashes. In the'present instance these cords are each rigidly secured at one end to the lower end of the upper sash by means of a staple 18,while they are detachably fastened at their other this end said lower sash isv provided in its opposite lower corners with a groove 19, in which is secured a slidably-mounted fastening-plate 2O by means of a screw 21 passing through a slot 22 therein and engaging'the sash. This plate has a downturned arm 23, which is forked to provide afsocket 24, in'which the end of the cord is engaged, and held by a knot V.25, that abuts against the'rear faceof the yends to the lowerend of the lower sash. To

when the sash is thrown to its uppermost position, as shown in Fig. 5. A vertically-disposed row of holding-pins 28 is arranged upon each side of the frame and extend in the grooves in the lower sash, said pins being disposed contiguons to the parting-beads, but spaced a slight distance therefrom, so as to permit of the insertion of the cord,but to prevent the passing of the knot,as shown in Fig.4.

For the purpose of locking the lower sash a sliding bolt 29 is provided,which is mounted in aslot 30,made in the window-frame for that purpose. The inner end of the bolt has an offset lug 3l, which is arranged to be moved into and out of a series of notches 32, made in the adjacent edge of the sash. The outer end of the bolt has an offset operating-handle 33, that projects through the slot 3i of a faceplate 35, secured to the frame, said slot being provided with an odset pocket 36, forming a retaining-shoulder 37.

The manner of operating the device is as follows: Under normal conditions the upper and lower sashcs are connected by the cords 16, so that each sash will counterbalance the other, and as a consequence when the lower sash is raised the uppersash will be lowered, and vice versa. Furthermore, when the lower sash is locked in its closed position by means ofthe bolt 29 the upper sash will be fastened against lowering. When it is desired to have the upper sash lowered and the lower one closed, it is only necessary to raise said lower sash to its highest position, whereupon the knots 27 of the cords will engage the stoploops 26, and the free ends of said cords will thereby be automatically disengaged from the fastening-hooks, as shown in Fig. 5. The lower sash may then be dropped to its normal position, and the two sashes will thus be at the bottom of the frame. In order to place both of the sashes at the top, the bot-tom sash is raised and locked by means of the bolt. The disengaged ends of the cords are then drawn and hooked behind the lower projections or pins 28, or if it is desired to lower the top sash and leave the lower one closed the cords are disengaged and fastened behind the pins, as shown in Fig. 4. In the practical embodiment of the invention the cords are made short enough so that when disengaged from the lower sash the lower end of the upper sash will be a slight distance above the sill, as illustrated in Fig. 5. In this manner said cords act as cushions to prevent any jar or shock occasioned by the sudden elevation of the lower sash and the consequent lowering and disengagement of the u pper sash. By this means it will be seen that the several objects mentioned in the preliminary portions of the specification are accomplished in a very simple manner and that the sashes may be adjustedsimultaneouslyorindependently. Furthermore, they can be locked so that they cannot be operated by a person on the exterior attempting to gain an entrance through the window. For this reason the specific position of the pulleys is important, as the cords passing over them are completely housed by the sashes, and therefore cannot be cut in order to release the upper sash. Under certain conditions, however, these pulleys may be arranged in other positions, and the invention is not to be limited to this precise disposition.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
